Good day!
I have a little problem running drbd.
System: Debian Squeeze 6.0.6
Kernel: 2.6.32-5-amd64
DRBD: 8.3.13-2
Config for home resource:
resource home {
on backup {
device /dev/drbd1;
disk /dev/sda5;
address 78.47.3.54:7789;
meta-disk /dev/ram0[14];
}
on backup2 {
device /dev/drbd1;
disk /dev/sda4;
address 78.47.3.86:7789;
meta-disk internal;
}
}
ram0 - 2Gb Size
I make the following actions:
# drbdadm create-md home
# /etc/init.d/drbd start
Then I see the following:
root at backup2 /etc/drbd.d # cat /proc/drbd
version: 8.3.7 (api:88/proto:86-91)
srcversion: EE47D8BF18AC166BE219757
1: cs:Connected ro:Secondary/Secondary ds:Inconsistent/Inconsistent B r----
ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:b oos:4293787648
Then I started sync:
root at backup /etc/drbd.d # drbdadm -- --overwrite-data-of-peer primary home
root at backup /etc/drbd.d # cat /proc/drbd
version: 8.3.7 (api:88/proto:86-91)
srcversion: EE47D8BF18AC166BE219757
1: cs:SyncSource ro:Primary/Secondary ds:UpToDate/Inconsistent B r----
ns:11232 nr:0 dw:0 dr:11436 al:0 bm:0 lo:0 pe:21 ua:0 ap:0 ep:1 wo:b oos:4293777088
[>....................] sync'ed: 0.1% (4193140/4193152)M
finish: 110:26:11 speed: 10,560 (10,560) K/sec
It's ok.
But when I try to mount /dev/drbd1 I see the following:
root at backup /etc/drbd.d # mount -t ext4 /dev/drbd1 /home/
mount: wrong fs type, bad option, bad superblock on /dev/drbd1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
And in dmesh I saw, that drbd started to sync only 4Tb:
[37354503.285925] block drbd1: Forced to consider local data as UpToDate!
[37354503.285972] block drbd1: Creating new current UUID

[37354511.724676] block drbd1: Began resync as SyncSource (will sync 4293787648 KB [1073446912 bits set]).
I tried to use flexible-meta-disk, but with no luck.
Can you help me to solve this problem?
Thank you!
